no square root of 9 is 3 which is rational -- to be more specific: an irrational number is a number that cannot be expressed as a fraction. Pi, for example, is one of these numbers. If a number is not a perfect square (4, 16, 9, 144, 225, etc.), then it's square root is likely to be an irrational number. For example, the square root of 2 (1.41421356...) is an irrational number because it cannot accurately be expressed as a fraction.
The square root of 225 is 15. This is because the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 15 multiplied by 15 equals 225. Therefore, the square root of 225 is 15.
Yes, the square root of 225 is ± 15 because 15 x 15 = 225 AND -15 x -15 = 225
± 15
The same way you find the square root of any number. The fastest way would be to type 225, followed by the square root key, in a calculator.
Neither, it is an imaginary number and imaginary numbers are neither rational nor irrational.
If you mean the square root of 196/225 then it is 14/15 which is a rational number because it can be expressed as a fraction.
The square root of 225 is 15, which is a rational number.
The square root of 225 is 15, which is NOT an irrational number.
Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.
yes it is

-225 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Yes, 225 squared is a rational number.
No because 225 is an integer and all whole numbers are rational
No, the best way to figure this out is to plug into a scientific calculator and if the answer you get has a square root around you know its irrational.
The square root of 225 is 15.
